How about a Morningstar relay driver? I have not done this exact thing
before.but similar things.

I hope this makes sense.

I was just about to suggest the same thing Mac suggested. Any 120 V relay would
work. Just wire it in parallel with the auxiliary relay that is shutting the
inverter off. When the AC input is energized, the relay closes, and your
inverter turns on. I like using a relay that has a base. I trust

To avoid power relay, how about adding a voltage sensing coil on the AC
input and have an NC contactor that opens on voltage in series with the
inverter shutdown circuit. This should interrupt the inverter shutdown any
time the generator is on.

I've done the AC relay idea as well, on Schneider that didn't have the
easy off switching like the Outbacks. The problems are:
1) Much bigger relay, much higher current on the control side as well.
It required a relay for the relay.
2) If there's a malfunction, you are messing with the main
Hi RayThis house won’t have an AGS, manual start only. And your comments exactly, having to wait until the next day when hopefully there is enough sun to charge the battery is iffy. Or they could do the inverter bypass switch. Again I’m back to why is it a worse idea to install a relay on the AC?
The aux off is only if the generator doesn't start. You need to set the
gen start voltage higher. Aux off is last ditch shut down, set for 44v
for lead acid, or 47 to 49v, depending on the battery and inverter.
Hopefully DC coupled PV will raise the voltage enough to turn the
inverters back
HI All,
I wanted to revisit this thread for one reason.
If you turn off the inverter at the remote on/off with the AUX relay, then
starting the generator won’t have any impact as the inverter is off.
So someone will have to go and reset the AUX relay.

If you do a relay on the AC output,
They did not anticipate the use with Lithium battery chemistry which is mostly
discharged at 12.7V, and that happens to be the fully charged resting voltage
of lead batteries.
Seems as though by now manufacturers should have increased the LBCO voltage
range in the software.

Hi Mac;
I've used the aux control on charge controllers to turn on/off the FX
inverters, just as you planned. Works fine, and solves the LBCO
programming issue.
Now, if someone from the manufacturing side could PLEASE explain why
they limited the LBCO on all these inverter models.
Mac,
I think you've got an elegant solution to the problem. All you need is
an inexpensive relay and to program the Aux output for loadshed. I
believe shutting down the inverter with the remote on/off contacts is
actually less stressful on the inverter than opening a relay or
contactor on
Hello Wrenches,
I'm trying to solve an issue with an older Outback FX system. It's a quad
stack of Outback 3648 FX inverters and he has a couple of Fortress eVault
and an unreliable generator. The LBCO setting can't go high enough to cut
out before the eVaults cut out so he occasionally will
